Shrinking Ultraviolet Light: A Breakthrough for Photonic Chips
Harvard University researchers achieve record UV power on-chip using advanced lithium niobate engineering
Ultraviolet (UV) light has long occupied a paradoxical position in science and engineering. While it is naturally abundant from the sun, its controlled, high-efficiency generation at small scales has proven exceptionally challenging. Yet UV light is indispensable across a wide array of modern applications, from sterilization and biochemical analysis to advanced semiconductor manufacturing.
